I just started watching Samurai Gun, and I have but one thing to say.
Ow.
I haven't been able to finish the first episode yet - I'm at the part with the charming "blood spurting" sound effect. Ow. I almost stopped at, oh, the second or third shot of the entire series - you'll probably know the one when you see it.
I have not yet determined if this burns worse than Burst Angel yet. I'll need a second opinion. Maybe I can inflict this on Stacey and Thomas without warning them. I'm so evil sometimes. I don't think they've forgiven me for Cat Soup yet.
[EDIT] I should note that this release does, in fact, contain copious amouts of blood, guns, and whores.
